Excuse my ignorance, but I don't know what a 'final' and a 'C1969' are?

Find yourself a radio butcher at the truck stop. He'll squeeze every last
ounce of harmonic energy out of the radio and it will swing real good on
his special Dozy Test Set.

I have a 25 on my shelf collecting dust. Looks like half an inch and growing...

I prefer the longevity of a stock radio driving a two device amp on low.
